Nambu-Jona-Lasinio Theory and Dynamical Breaking of Supersymmetry
Nobuhito Maru
TL;DR
This paper reviews a new mechanism for dynamical supersymmetry breaking triggered by D-term vacuum expectation values, drawing parallels with models like Nambu-Jona-Lasinio and BCS superconductivity.
Contribution
It introduces a novel D-term based mechanism for supersymmetry breaking, expanding understanding of nonperturbative effects in supersymmetric theories.
Findings
Supersymmetry is broken by a nonzero D-term vacuum expectation value.
The D-term vacuum expectation value is obtained as a solution to a gap equation.
The mechanism is analogous to Nambu-Jona-Lasinio and BCS models.
Abstract
A recently proposed new mechanism of D-term triggered dynamical supersymmetry breaking is reviewed. Supersymmetry is dynamically broken by nonvanishing D-term vacuum expectation value, which is realized as a nontrivial solution of the gap equation in the self-consistent approximation as in the case of Nambu-Jona-Lasinio model and BCS superconductivity.
